One of the minor side-effects of the way ColdSpring easily handles
more and more complexity is that I found my ColdSpring XML file got
out of control unless I took an organised approach to the layout.
My first few ColdSpring sites had about 20 CFCs or so to manage, and
without thinking much, I'd just add a new CFC to the bottom of the XML
and that would be fine. But then i built a site that had many more
CFCs than that, and i found my XML file got unmanageable. I was
getting errors because i was duplicating the XML definition of CFCs
and omitting some altogether. I found i had to be more organised
than the XML equivalent of the shoebox filing system.
I tried putting the CFCs into the XML file in alphabetical order, and
that didn't really work. It improved things a bit, but what worked
most was to put CFCs related to different parts of the application
together - all the USER cfcs together and all the CONTENT cfcs
together and all the CATALOG cfcs together etc. With comments between
the sections of the XML file, so they are easy to find.
THEN Coldspring showed its magic. It happily handled the management of
hundreds of CFCs, all their dependencies, locations, how they are to
be instantiated, and all i ever had to do in a calling page was
something like:
<cfset UsersDAO = application.beanfactory.getbean("UsersDAO")> and i
never had to worry again about how to instantiate it, where it was,
what other cfcs it depended on, where to find them, whether
parameters or other objects were required in the init() method, etc.
If i ever change my hard drive layout - move my CFCs around - there's
only one file that ever needs to know where to find them - the
coldspring XML file.
As i said, MAGIC! All i have to do is 'hey Coldspring - give me a
UsersDAO object' and it knows what to do , and just does it!
